From vaulted and drafty to warm and cozy the great room of this Lake Oswego home was brought down to size. A ceiling was added at a conventional nine-foot height. The interior design features a television. niche above the slate dressed fireplace with a wraparound wood mantel that melds seamlessly into the custom display and entertainment storage. Airspace from the former vault is now a light filled, quiet library with a comfortable seating area, ample bookshelves and full height stacking glass doors.
